Index is one of the choices. I have to choose where I would find those things. DO you know where I would find the World War 1 question at?

Answer 1

I'd sure look in the Index under WWI -- and then read the part about the beginning of the war.

Answer 2

Where would you find further information about a specific topic?

Answer 3

Any place else in the book -- the Table of Contents, Glossary, and of course the text itself.
